ABSTRACT
BACKGROUND: Low-impact laparoscopy (LIL), combining low-pressure insufflation and microlaparoscopy, is a surgical technique that is still not widely used and that has never been evaluated for the management of acute appendicitis. The aim of this study is to assess the feasibility of an LIL protocol, to compare postoperative pain, average length of stay, and in-hospital use of analgesics by patients who underwent appendectomy according to a conventional laparoscopy or an LIL protocol. STUDY DESIGN: Patients presenting with acute uncomplicated appendicitis who were operated on between January 1, 2021, and July 10, 2022, were included in this double-blind, single-center, prospective study. They were preoperatively randomly assigned to a group undergoing conventional laparoscopy, ie with an insufflation pressure of 12 mmHg and conventional instrumentation, and an LIL group, with an insufflation pressure of 7 mmHg and microlaparoscopic instrumentation. RESULTS: Fifty patients were included in this study, 24 in the LIL group and 26 in the conventional group. There were no statistically significant differences between the 2 patient groups, including weight and surgical history. The postoperative complication rate was comparable between the 2 groups (p = 0.81). Pain was reported as significantly lower according to the visual analog scale 2 hours after surgery among the LIL group (p = 0.019). For patients who underwent surgery according to the LIL protocol, the study confirms a statistically significant difference for theoretical and actual length of stay, ie -0.77 days and -0.59 days, respectively (p < 0.001 and p = 0.03). In-hospital use of analgesics was comparable between both groups. CONCLUSIONS: In uncomplicated acute appendicitis, the LIL protocol could reduce postoperative pain and average length of stay compared to conventional laparoscopic appendectomy.

AIM: The aim of the study was to determine the preoperative predictive factors of overall survival, relapse-free survival, and peritoneal carcinomatosis in obstructive colorectal cancer. METHODS: Data from patients undergoing emergency surgery for obstructive colorectal cancer at our center between 2004 and 2016 were extracted retrospectively from our health records. Several preoperative parameters were used to predict survival and peritoneal carcinomatosis using univariate and multivariate analysis, and ROC curves. RESULTS: A total of 107 patients with obstructive colorectal cancer were included. Five-year relapse-free and overall survival rates were 14% and 28%, respectively, with 15% peritoneal carcinomatosis. Univariate analysis showed that age ≥ 83 years old, preoperative ASA score ≥ 3, initial hemodynamic instability, and CRP > 18.3 mg/L was significantly associated with worse relapse-free and overall survival. In a multivariate analysis, only age > 83 years (HR = 1.75; HR = 2.16, for relapse-free and overall survival status, respectively) and hemodynamic instability (HR = 7.29; HR = 6.55) were confirmed in the multivariate model. Global peritoneal carcinomatosis was significantly associated with synchronous liver metastases in the multivariate model (OR = 4.56), and synchronous peritoneal carcinomatosis only was significantly associated with platelet to lymphocyte ratio (PLR) > 269 and synchronous liver metastases in the multivariate model (OR = 0.003; OR = 7.26). CONCLUSION: Synchronous liver metastases are prognostic risk factor for global and synchronous peritoneal carcinomatosis whereas PLR > 269 was a significant protective factor for synchronous peritoneal carcinomatosis only for obstructive colorectal cancer. Age > 83 years and initial hemodynamic instability were key preoperative prognostic risk factors for worse relapse-free and overall survival. Prognostic usefulness of blood cell ratios for mortality and peritoneal carcinomatosis warrants further investigation.

Mycotic aneurysm is a life-threatening disease often caused by Salmonella, Staphylococci and Streptococci species. Interestingly, Escherichia Coli (E. Coli) is described as a rare causative agent. We report the case of a patient who developed a mycotic aortic and ruptured left iliac aneurysm due to E. Coli. The patient developed a secondary aortic graft infection due to a mesenteric ischemia with fecal peritonitis. A literature overview of the current knowledge on mycotic aortic aneurysms specifically due to E. Coli is discussed including the clinical characteristics of patients, the management of the disease and the post-operative outcomes.
